Why wasn the recording date for the Spanish versions of Andante, Andante and Happy New Year (Felicidad) mentioned in the book?
The answer is obvious – these dates were unavailable. This is a good example of the sometimes random nature of which dates I could find or not: Frida just happened to mention the recording date for the Spanish versions of When All Is Said And Done and Slipping Through My Fingers in a 1981 radio interview I was lucky enough to get access to during my research.
